Instructions
Navigate to the installation drive of "Battlefield" Bad Company 2." For most users, this will be the "C:" drive. In the "User" directory, navigate to and open the "Administrator" folder.
Inside the "Administration" folder, open the "My Documents" folder and locate the "Battlefield: Bad Company 2" directory.
Inside the "Battlefield: Bad Company 2" folder, locate the "Settings.ini" text file. Right-click on the file and select "Properties."
Inside the "Properties" context window, disable the "Read-Only" option, making the file editable. Click "OK" to save the setting.
Open the "Settings.ini" text file using a free text editor, such as Wordpad.
Find the line of code that begins "MainQuality=" and "Low" or "High" will follow the equals sign. Alter the code to read "MainQuality=Custom."
Find the line of code that reads "bloom=true." Change it to read "bloom=false" and save your changes.
Close the text file and right-click on it within Windows Explorer. Select "Properties" from the drop-down menu, and left click to open the Properties window. Check the "Read-only" button in the lower portion of the window and click "OK."
Launch the game, and the bloom effects that control the fog, smoke and haze should now be disabled
